7 Claims. (Cl. 155-'-106) This invention relates to articles of furniture and more particularly to articles of repose for supporting the body of a person, wherein a seat and a backrest being movable relative to each other may be, brought from a sitting position into a reclined position and vice versa.

An object of the invention is to provide a reclining chair of above described type with an improved mechanism for controlling the movements of the back-rest and the seat in dependence on each other.

Another object of the invention is to provide a reclining chair of above described type with an improved mechanism for controlling the relative movements of the back-rest, the seat and a leg-rest.

A further object of the invention is to improve on the art of reclining chairs as now customarily made.

Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanyingdrawings forming part of this specification, wherein:

Fig, 1 is a side elevational view of a reclining armchair, according to the invention,. a portion of a side Wall being broken away,

Fig. 2 is a side elevational .view. of the chair shown in Fig. 1 wherein, however, the movable elements of the chair are in the extreme reclined position,

Fig. 3 is a side elevational view of a further embodiment of the reclining armchair, according to the-invention, a portion of a side wall being broken away,

Fig. 4 is a side elevational view of the chair shown in Fig. 3 wherein, however, themovable elements of the chair are in the extreme reclined position,

Fig. 5 is a side elevational view of still another embodiment of a reclining chair according to. the invention, a portion of a side wall being broken away, and

Fig. 6 is a side elevational view of the reclining chair shown in Fig. 5 wherein, however, the movable members of the chairare in the extreme reclined position.

Referring now to Figs. 1 and 2, 10 generally indicates a support having side walls 12 and 14 connected with each. other by cross bars 16 and a rear wall18.

A back-rest 29 is swingably mounted on the support 1.0 at 22. Therear portion. of a. seat 24 is pivoted to the back-rest 20 at 26. Thepivotalconnection 22 between the back-rest. 20 and the; support 10- is below the pivotal connection 26 between the seat 24 and the backrest 20., A controlling. member. in the shape of a plate 28.-is swingably mounted on the support 10 at 30. The rear end of a first controlling link 32 is. pivoted to the seat. 24 at 26.;in coaxial alignment. with the pivotal connection between the seat 24 and: the back-rest20t The front end of said first controlling link 32, is pivoted to the controlling member 28 at 34. The lower end of a second controlling link 36 is pivoted to. the controlling plate 28" at 38'. The upper end of said second controlling link36 is pivoted to the seat .24 at 40'- Thus, upon a movement of the back-rest 20 from the sitting position shown in Fig. 1 into the reclined'position 2,909,214 Patented Oct. 20, 1959 shown in Fig. 2 the controlling member 28 is swung by the firstcontrolling link 32 from the position shown in- Fig. 1 into the position shown in Fig. 2, and the seat 24 is brought through the medium of the second controlling link 36 into the position-shown in Fig. 2. In other words, there is a coordination between the movements of the back-rest 20 and the. seat 24 during a movement of said elements from the sitting position shown in Fig. 1 into the reclined position shown in Fig. 2 and vice versa.

The sitting position of the movable members of the chair is limitted by a stop 42. attached to the support 10 for abutting engagement with the seat 24. The extreme reclined position-of the movable members of the chair is limited by the upper edge 44 of the rear wall 18 cooperating with the back-rest 20.

The chair shown in Figs. 1 and 2 is equipped with a leg-rest 46. The movements of said leg-rest 46 are controlled in' dependence on the movements of the back-rest 20 and the seat 24 in the following manner: A first link 48 is swingably mounted on the seat 24 at 50. The rear end of a second link 52' is pivoted to the lower end of said first link 48 at 54'while' the front end of said second link 52 is pivoted to the lower end of the leg-rest 46 at 56. The front end of a third link 58 is pivoted at 60 to the upper end of the leg-rest 46 at a point spaced from the pivotal connection 56 between the leg-rest 46 and the second link 52. The third link 58 is pivoted at 62 intermediate its ends to the first link 48. The pivotal connection 62 is spaced from the pivotal connection 54 between the first link 48 and the second link 52. The front end of a fourth link 64 is pivoted at 66 to the first link 48- at a point located between the pivotal connections 62 and 50 of said first link 48 with the third link 58 and the seat 24 respectively. The rear end of the fourth link 64 is pivoted to the controlling plate 28 at 68. The upper end of a fifth link 70 is pivoted at 72 to an intermediate point of the forth link 64 and the lower end of said fifth link 70 is pivoted at 74 to the rearwardly projecting endof the third link 58.

Thus, when during above described movement of the backrest 20 and the seat 24 from the sitting position shown in Fig. 1 into the reclined position shown in Fig. 2 the controlling plate 28 is. swung about its pivot 30 on the support 10 from the position shown in Fig. 1 into the position shown in Fig. 2, the leg-rest is propelled forwardly and upwardly from the position shown in Fig. 1 into the position shown in Fig. 2 by means of above described link systems 48, 52, 58, 64 and 70 in depend ence on the movements of the controlling plate 28 and the seat 24. Thus, there is a coordinated relationship between the movements of the back-rest 20, seat 24 and leg-rest 46 when said members are moved from the sitting position shown in Fig. 1 into the reclined position shown in Fig. 2.

According to the embodiment shown in Figs. 3 and 4 again the back-rest is pivoted to the support 110 at 122 at a point below the pivotal connection 126 be-- tween the seat 124 and the back-rest 120.

Furthermore the controlling member 128' swingably mounted on the support 110 at 130 and its link connection- 136 with the seatl24 corresponds fully to the arrangement of the controlling member and the second link according to the embodiment shown in Figs. 1 and 2. Moreover, again the front end of a first controlling link 132 is pivoted to the swingable controlling plate 128 at 134. The rear endof said first controlling link 132, how

mechanism 148, 152, 158, 164 and 170 and the connection of the latter with the seat 124 and the controlling member 128 respectively corresponds fully to the leg-rest control of the embodiment shown in Fig. 1.

When the back-rest 120 is swung about its pivot 122 from the upright position shown in Fig. 3 into the reclined position shown in Fig. 4, the seat 124 and the leg-rest 146 are positively moved from the position shown in Fig. 3 into the position shown in Fig. 4 through the link mechanism described above.

According to the embodiment shown in Figs. 5 and 6 again the lower end of the back-rest 220 is swingably mounted on the support 210 at 222 at a point below the pivotal connection 226 between the seat 224 and the backrest 220.

The arrangement of the controlling member 228 is somewhat different from the arrangement of the corresponding controlling member of the embodiments shown in Figs. 1-4. According to Fig. 5 the controlling member is swingably mounted on the support 210 at 230. The pivotal connections 234 and 238 of the controlling member 228 with the first controlling link 232 and the second controlling link 236 respectively are above and to the left of the pivotal connection 230 between the support 210 and the controlling member 228 when the latter is in the position shown in Fig. 5. The rear end of the first controlling link 232 is pivoted to the backrest 220 at 229 at a point spaced from the pivotal connection 226 between the back-rest 220 and the seat 224. The upper end of the second controlling link 236 is pivoted at 240 to the seat 224. It will be readily understood that upon a movement of the back-rest 220 from the upright position shown in Fig. 5 into the reclined position shown in Fig. 6 the controlling member 228 is swung about its pivot 230 from the position shown in Fig. 5 into the position shown in Fig. 6. This swinging movement of the controlling member 228 furthermore results in a forward and upward movement of the leg-rest 246 connected with said controlling member 228 and the seat 224 through the links 248, 252, 258, 264 and 270 in the same manner as described above in connection with the embodiments shown in Figs. 14.

Thus, the embodiment shown in Figs. 5 and 6 likewise provides for coordinated movements of the back-rest 220, seat 224 and leg-rest 246 between a sitting position and reclined position. The sitting position is limited by the abutting engagement of the seat 224 with the stop 242 while the extreme reclined position is limited by the abutting engagement of the back-rest 220 with the upper edge 244 of the rear wall 218 of the support 210.

I have described preferred embodiments of my invention but it is understood that this disclosure is for the purpose of illustration and that various omissions or changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
